Rechargeable battery Trojan 31-GEL (12V, 102Ah)

Sealed (Gel) lead-acid battery technology.

The essence of the operation of a lead-acid battery is reduced to the transfer of lead sulfate, which covers both plates of the battery in a discharged state, under the influence of a direct electric current into metallic lead on the cathode:

PbSO ₄ + 2e \u003d Pb + SO ₄ ^2-

and tetravalent lead oxide on the anode:

PbSO ₄ - 2e + 2H ₂ O \u003d PbO ₂ + 4H ⁺ + SO ₄ ^2-

Charging the battery leads to the fact that the initially identical electrodes become chemically different and a potential difference appears between them. If the plates of a charged battery are connected with a conductor, then the reverse process will take place - a discharge, and an electric current will flow through the conductor.
